The Company has undertaken the following in satisfaction of this requirement.

A letter to all land owners within 2km of blasting operations was mailed on

21 September 2011. Additionally where land owner references and details were

not available, properties were visited and letters were hand delivered by

7 October 2011. The letter notified residents that blasting operations would

commence no sooner than 24 November 2011 and that all residents receiving the

letter were entitled to a property inspection by a suitably qualified, experienced

and independent person whose appointment has been approved by the Department

of Planning and Infrastructure and advised how land owners could request a

property inspection.

Nine residents responded requesting property inspections, with the inspections

being completed in December 2011.

A second letter was mailed on the 3 June 2012, as it was noted that due to delays

with executing the Project a number of new residences have been built within the

prescribed area. Further, a number of residents who did not respond to the first

letter had expressed interest in having their property inspected following the

completion of inspections in December 2012. A database is being maintained

regarding those residents who have requested a property inspection, with property

inspections scheduled to occur prior to the start of Project-related construction.

Copies of the relevant reports were provided to the owners/residents of the

inspected properties. Digital copies will be provided to the Department of

Planning and Infrastructure following the completion of all property inspections.

6.1.2 Property Investigations

Condition 3(9) of MP 10_0054 identifies the procedure for conducting property investigations

in the event of a complaint related to blasting-related structural damage (Table 1). The

Company has committed to conducting property inspections and investigations, as the need

arises, in accordance with the above conditions.

In the event that blasting-related property damage is identified and that damage is conclusively

determined to be Project-related, the Company will implement the following procedure.

A suitably qualified, experienced and independent person whose appointment has

been approved by the Director-General of DP&I will be engaged to determine

what remedial action is required to initially stabilise the identified damage and

appropriately remediate it. A copy of the report will be provided to the landowner

for consideration.

If both the landowner and the Company agree with the recommendations, the

Company will, in consultation with the landowner, engage a suitably qualified

builder to complete the recommended work in a reasonable timeframe.

Should either or both the landowner and the Company not agree with the

recommendation, the Company would seek to negotiate with the landowner to

reach a mutually agreeable solution.

Should a mutually agreeable solution not be able to be reached, either the

Company or the landowner may request that the issue be resolved in accordance

with the independent review process identified in Conditions 4(3) and 4(4) of

MP 10_0054.

6.2 BLAST MITIGATION MEASURES

6.2.1 Introduction

Condition 3(11)(c) of PA10_0054 identifies that this document describes the blast mitigation

measures that will be implements to ensure compliance with Conditions 3(6) to 3(10)

(Table 1). This section has been prepared in part satisfaction of that requirement. Measures

that will be implemented in relation to public notification and blast monitoring are presented in

Sections 6.3 and 7 respectively.

6.2.2 Blast Design

Commitment 4.13 (presented in Appendix 5 of MP 10_0054) identifies that all blasts will be

designed by a suitably qualified and experienced blasting engineer.

In addition, until such time as a suitable site law has been established, each blast will be

designed in a manner that ensures compliance with blast criteria identified in Condition 3(6)

using industry standard formula.

Once sufficient blast monitoring data has been collected, a suitable blasting site law would be

developed in accordance with industry practice and all subsequent blasts would be designed to

ensure that the blast criteria identified in Condition 3(6) are complied with (Table 1).

Finally, the paste will be designed to withstand blasting operations immediately adjacent to the

backfilled stopes. Notwithstanding this, the Company will ensure that the blast engineer has the

relevant experience for designing blasts associated with paste fill and that all blasts are designed

to minimise the impact on the structural integrity of the paste fill.

6.2.3 Blasting Hours

All blasting operations will be undertaken during the hours identified in Condition 3(7), as

follows.

Surface blasting will be undertaken only between the hours of 9:00am to 5:00pm,

Monday to Friday, excluding public holidays, except for emergency or safety-

related reasons and only after a written request for approval has been provided to

the Environment Protection Authority.

BIG ISLAND MINING PTY LTD BLAST MANAGEMENT PLAN

Dargues Reef Gold Project Report No. 752/13 – Revision 2

10 Spectrum Acoustics Pty Limited

Underground blasting may be undertaken at any time. It is noted that because the

Dargues Reef Gold Mine is a small mine with limited development headings, that

restricting underground blasting operations to particular times of day will not be

practicable. However, in recognition of the concern of Office of Environment and

Heritage in relation to this matter, the Company will ensure that underground

blasts are undertaken, where practicable, at shift change, namely between 5:30am

and 6:30am and 5:30pm and 6:30pm.

6.3 PUBLIC INFORMATION RE BLASTING OPERATION

Condition 3(13)(d) of MP 10_0054 requires that this document describe the measures that will

be implemented to ensure that the public can get up-to-date information on the proposed

blasting schedule within the Project Site. These measures will include the following.

Continued operations of the Community Information Line (0415 682 917), a 24-

hour, 7 day per week service, where up-to-date information on the blasting

schedule will be available. The Community Information Line will operate for the

life of the Project and the telephone number will be advertised in local newspapers

at least quarterly and on the Project Website

One or more blast notice boards will be installed at the entrance to the Project Site

to advise Project personnel and visitors of the blasting schedule. These boards

will be visible from Majors Creek Road.

Indicative blast times will be provided on the Project website.

7. B L AS T - R E L AT E D M O NI TO RI N G

Condition 3(13)(d) of MP 10_0054 requires that this document describe the blast monitoring

program that will be initiated to evaluate the performance of the Project.

As a minimum, each blast, whether surface or underground, will be monitored for ground

vibration, and in the case of surface blasts, blast overpressure at the nearest non-Project related

residential receivers to the blast, subject to landholder agreement. The proposed monitoring

locations are indicated in Figure 1 and Table 4 presents the ownership details for each

monitoring location.

Table 4 Blast Monitoring Locations

R29 B & C James

R108 J & K Spring

In addition, until sufficient blast monitoring data is available to establish a blasting site law,

additional blast monitoring will be undertaken at suitable locations within the Project Site.

The blast monitoring locations will be reviewed and where necessary modified as a result of

changes to the geographical location of blasting or changes to regional land ownership.

All blast monitoring instrumentation will be installed, calibrated and maintained in accordance

with both AS2187.2 - 2006 and the manufacturer’s specifications. In addition, the Company

will investigate the feasibility of installing blast monitors capable of real-time relay of ground

vibration and overpressure results to relevant site personnel. Where real-time transmission is

not possible, data will be downloaded at the monitoring site as soon as possible after each blast.

8. E VAL U AT I O N O F C OM PLI AN C E

Upon receipt of blast monitoring data from each blast, the responsible personnel (see

Section 13) will record the measured blast overpressure and ground vibration parameters and

compare them with the relevant blast criteria identified in Condition 3(6) of MP 10_0054

(Table 1).

9. C OM P L AI N T S H AN D L I N G AN D RE SP O NS E

The Environmental Management System includes a detailed complaints management procedure.

This sub-section records the procedures that would be implement following receipt of a blast-

related complaint.

Blast-related complaints may be received either via one of the following methods.

Directly via the 24-hour, 7 day per week Community Information Line. This

number is currently 0415 682 917, however, the Company will implement a free

call number during the initial stages of the Project. This number will be

advertised widely in the local media, on signage at the Project Site entrance and

on the Project web site.

Directly via a dedicated email address ([email protected]) which will be

Following receipt of any blast-related complaint, it would be recorded in the complaints register

and the Company would implement the following procedure.

1. The complaint will be reviewed by the Environmental Supervisor or their delegate

to determine the nature, date and time of the complaint and the activities occurring

within the Project Site at that time, in particular, whether a blast was being

undertaken at the time alleged.

2. In the event that a blast was being undertaken around the time of the complaint,

the Environmental Supervisor or their delegate would review the results of the

blast monitoring and prepare a preliminary investigation report.

3. A copy of the resulting report would be made available to the complainant and the

Environmental Supervisor or their delegate would contact the complainant to

discuss and attempt to resolve the complaint.

4. In the event that the procedures identified in Steps 1 to 3 above resolve the issues

raised, no further action would be taken. In the event that the complaint is not

resolved, then further blast monitoring at the complainants residence would be

undertaken in accordance with the procedures identified in Section 7. Following

monitoring of a suitable number of blasts a monitoring report would be prepared

outlining the results of that monitoring and provided to the relevant government

agencies and the complainant.

5. Should the monitoring report indicate that no exceedance of the criteria identified

in Condition 3(6), the Environmental Supervisor will continue to consult with the

complainant in relation to managing impacts at the Complainants residence.

6. Should the monitoring report indicate an exceedance of the criteria identified in

Condition 3(6), the Environmental Supervisor will notify the relevant government

agencies in accordance with the procedures identified in Section 11 and

implement the procedures identified in Section 10. In addition, the Environmental

Supervisor will continue to consult with the complainant in relation to the

complaint.

7. In the event that multiple complaints are received from the same individual(s) and

the Company can demonstrate:

– at least three periods of blast monitoring at the residence in question, all of

which demonstrated compliance with the criteria identified in Condition 3(6);

and

– there is documented evidence of a genuine attempt by the Company to discuss

the issue and seek a resolution with the complainant;

then the Company may, in consultation with the relevant government agencies,

limit responses to further complaints to Steps 1 to 3 above.

In the event that blast monitoring identifies an exceedance of the criteria identified in

Conditions 3(6), the exceedance will be investigated to determine the likely cause. The

investigation will seek to determine:

whether the exceedance of the criteria was directly related to a source associated

with the Project or if environmental factors contributed to the exceedance;

the primary cause of the incident;

any contributing factors which led to the incident;

whether appropriate controls were implemented to prevent the incident; and

corrective and preventative measures that may be implemented to prevent a

recurrence of the incident.

Corrective and/or preventative actions will be assigned to relevant Company personnel. In

addition, the blast parameters and blast site laws would be reviewed in light of the monitoring

results and adjusted as required to ensure no further exceedance of the criteria. Actions will be

communicated internally through planning meetings and toolbox talks and outstanding actions

will be monitored for their effectiveness upon completion.

A copy of the investigation report and regular updates on the status of the identified corrective

and/or preventative actions will be provided to the relevant government agencies and, if

required, the complainant, in accordance with the procedures identified in Section 11. In

addition, a copy of all report will in included in the Annual Environmental Management Report.
